Blockchain ToBTC API not returning Php variable

Question

I am having trouble getting the Blockchain ToBTC API to return the value of a PHP variable.

API = https://blockchain.info/tobtc?currency=USD&value=500

$total_price+=$price;

$btc_total = echo "https://blockchain.info/tobtc?currency=USD&value=$total_price";

How can I make this happen?

Seems like you have a syntax error in your code use this line to print url,

echo $btc_total = "https://blockchain.info/tobtc?currency=USD&value=$total_price";

You should use curl to get value from above url.

<?php
    $total_price += $price;
    $curl = curl_init('https://blockchain.info/tobtc?currency=USD&value='.$total_price);
    curl_setopt($curl, CURLOPT_FAILONERROR, true);
    curl_setopt($curl, CURLOPT_FOLLOWLOCATION, true);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false);
    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
    $result = curl_exec($curl);
    echo $result;
?>
